If you haven't purchased books for all your classes, you should do so soon. Our partner bookstore is open, offering both an efficient purchasing experience and free shipping to the contiguous United States on orders of $99 or more on items purchased from the store (not necessarily from a third party seller) from now until Wednesday August 3 at 10:00 pm Pacific Daylight Time. Of course, you can still use other sources to hunt for bargains if you wish. Read this post to learn more.
